Senior QA Engineer Location - UK South Becoming part of our team Own Quality. Enable Speed. Drive Better Engineering Practices. In the words of one of our senior clients recently… "Market Research has changed more in the last 3 years than the previous 40" We are looking for an experienced Senior QA Engineer to help strengthen quality across our products and platform while enabling faster and safer delivery. You will work within a Scrum team alongside developers, product owners and DevOps engineers, helping ensure quality is built into the development process rather than tested at the end. In our engineering model, developers own most automated testing, including unit, API, integration and performance tests. QA focuses on exploratory testing, risk analysis, end-to-end behaviour and ensuring the overall quality of our systems. This is a hands-on role for someone who enjoys working closely with developers and influencing how quality is approached within modern engineering teams. What you will be doing Working in a microservices-based .NET environment with CI/CD, you will help teams deliver software frequently and safely. Your responsibilities will include: • Working within Scrum teams to embed quality thinking early in the development lifecycle., • Supporting developers in building strong unit, API, integration and performance testing., • Promoting shift-left practices to detect issues earlier in development., • Performing exploratory, risk-based and end-to-end testing where automation alone is insufficient., • Identifying system risks, edge cases and integration issues early., • Contributing to improving test automation frameworks and CI/CD testing workflows., • Helping reduce flaky tests and improve confidence in automated pipelines., • Participating actively in refinement, planning and retrospectives, ensuring quality considerations are included. What success looks like Success in this role means teams are able to release software frequently and confidently, supported by reliable automation and strong engineering practices. You will help ensure that: • Developers take ownership of automated testing., • Defects are found early rather than late in the process., • QA effort focuses on risk and system behaviour, not repetitive manual testing., • Automated tests provide fast and trusted feedback in CI/CD pipelines. Quality discussions focus on risk, impact and outcomes, not simply test counts or pass rates. Technical background You should have experience working in Agile teams where quality is a shared engineering responsibility. We are particularly interested in candidates who understand shift-left testing and developer-led automation. Experience with the following is desirable: • Test automation in .NET / C# environments, • UI automation tools such as Selenium, • BDD frameworks such as Reqnroll, • Test frameworks such as NUnit, xUnit or MSTest, • API testing using REST, Postman or Swagger/OpenAPI, • CI/CD pipelines and automated testing workflows, • SQL and relational databases such as SQL Server or MySQL, • Cloud environments, ideally Microsoft Azure, • Microservices architectures Experience with Docker, contract testing, performance testing tools such as K6, or feature flag driven development would be beneficial. Collaboration and influence While this is not a people-management role, you will act as a senior quality voice within your team. You will: • Work closely with developers to improve testing practices., • Review and guide automated tests written by developers., • Share quality engineering practices with other QA engineers across teams. Why join us You’ll be joining a modern engineering environment built around CI/CD, microservices and cloud technologies, where quality is treated as an engineering responsibility rather than a final gate. This role offers the opportunity to work in teams where: • Developers actively participate in testing, • Automation is central to how we deliver software, • QA focuses on insight, risk and improving engineering practices If you enjoy working closely with developers, improving testing practices, and helping teams deliver high-quality software faster, this is a role where you can make a real impact.

Note: no agencies/consultancies, must be in the UK with right to work We're building the digital infrastructure that makes clean energy work in the real world. Seventy million machines run on diesel. The alternatives exist. But the operations are complex, the supply chains are still emerging, and for most companies the transition feels risky. That's the problem we're solving. Logiq Systems builds the operational intelligence layer that makes clean energy work in the real world. One platform for fuel suppliers, rental companies, and asset operators to deploy, monitor, and optimise hydrogen, battery, solar, and alternative fuel systems — at the scale and reliability that industries actually need. We're live across construction, events, and industrial sectors with customers including Toyota, Balfour Beatty, Acciona, Sunbelt Rentals, and Protium. The technology works. Now we're scaling the team that scales the business. If you want to work on infrastructure that matters, in a company early enough that what you do shapes the industry, we'd like to hear from you. UNITED KINGDOM, REMOTE / FULL-TIME Role Summary: We are looking for a Senior Software Engineer (full-stack) to develop the Logiq platform. Working closely with our Head of Product, you will be responsible for building software that forms the core of our main business, as well as defining the long-term technical direction of Logiq Systems. Who we are today: Logiq Systems was founded in 2020 and is currently a team of five. Aran Bates and Ben Lindley are the founders, two friends turned colleagues. We are both dads of kids less than 5 years old (two each). Having both worked on this for two years self-funded (although now venture backed) we are driving a huge market shift in off-grid energy. While it is one that won't change with the speed of the AI bubble - this is infrastructure and hardware, not some Al wrapper over ChatGPT - it delivers sticky and lasting change with our customers and the industries we touch. As a team our passion and mission is improving the world around us, making it better for people and the planet. Our purpose pushes us to be the force of change in this industry. Not just in environmental sustainability by making the world less polluted from carbon, noise and poor air quality, but also in creating a supportive company flexible to the realities of modern life. A company with a diverse, equal, and respectful workforce. What does that really mean though? Well we recognise that talent can exist anywhere in the UK and that people have life commitments that can overlap with traditional 'core hours'. We are remote-first: As a team we are spread across the UK from Edinburgh to London, this means we can work with the best people out there. We also recognise the importance of building a sense of team, meeting regularly (at least once a quarter) and put a lot of emphasis into team building in the 'virtual' work environment also - e.g. daily team video calls, non- work Slack channels such as one specifically for sharing the music we are listening to. Although for this role there is a preference to have a candidate within around an hour of travel to Edinburgh or Oxford to work with the founders or the Head of product in person more regularly. Flexible working: To manage the interface of life and work we operate a flexible working policy, at the start of every week we have a whole team standup and in that we clearly communicate as a team what commitments people have that might cut into the working day or lead to a hard stop at the end of the day, so that as a team we can ensure that life and work fit together. Supporting women and primary carers in tech: Both Ben and Aran fully recognise the importance of building a supportive working environment for women and parents so they can continue a career, while remaining supportive and attentive to both kids and work. This has been heavily influenced through their experience as fathers and with partners who continue to have successful careers, while sharing parenting loads. The team we are building: The team we want to build is one where we are: • Passionate about making a difference. We are pushing change through a traditional market there meaning there are naysayers, so it is very important we have strong belief in the change we are driving., • Flexible and comfortable with ambiguity. We must be flexible as the market is early and developing. You will be shaping a new offering in the clean energy industry right from the start!, • Extremely self-motivated with a strong work ethic. We are a small team and need people to own their work. We also work hard because we love what we do!, • Fun! We need to enjoy what we do, while still being proud about the quality of our work., • Humble, authentic, and honest. We give credit where credit is due. We can respect, support and celebrate others for the value they bring., • Comfortable being challenged. We believe in creating an environment where we feel comfortable and safe enough for ideas to be challenged in a constructive manner., • Curious. Curiosity drives improvement and innovation. Always ask why. The Role: As a Senior Software Engineer, you will be responsible for the long-term technical direction of the Logiq platform and products, which provide real-time operational intelligence for connected clean energy assets. You will be designing and developing new products, features and improvements to the Logiq platform, delivering value to our growing customer base and the key capabilities required to evolve our growing business. As a senior member of the team, you will also have direct input into the product direction, working closely with the Head of Product to shape how Logiq develops as we scale. You will also be the champion of software engineering best practices across Logiq Systems. A few of your responsibilities: • Design and develop full-stack features using React, Python, PostgreSQL and serverless technologies (AWS Lambda, Fargate)., • Design and implement RESTful APIs and event-driven systems., • Maintain, extend and improve optimisation, alerting and forecasting models., • Implement and maintain CI/CD pipelines., • Ensure high-quality code through peer reviews, automated testing, documentation and adherence to software development standards., • Take ownership of the technical architecture and engineering processes., • Collaborate closely with a small startup team. To thrive in this role: We expect you to: • Be comfortable with variety and shifting priorities. Early-stage companies require adaptability, and you'll be working across very different types of tasks., • Take ownership of outcomes, not just tasks. You'll be given problems to solve, not always detailed instructions on how to solve them. We'll provide context and support, but you should be confident running with work and coming back with solutions or thoughtful questions., • Balance quality with speed. Early-stage work requires knowing when "good enough" is better than "perfect but late"., • Ask questions and challenge ideas respectfully. We value curiosity and constructive input across the team. We value people who bring their perspective and aren't afraid to ask "why?" or "what if we tried...?". Equally they are comfortable with their ideas also being respectfully questioned. We put the problem being tackled in the middle. What you'll need to do this job: • Full-stack: Proven experience in full-stack software development. We are using Python (REST & GraphQL) for the backend, React for the frontend., • Cloud architecture design: Proven experience in scalable cloud architecture design., • API design: Solid understanding API design (REST & GraphQL)., • SQL/NoSQL databases: Experience working with SQL (Postgres) and / or NoSQL databases., • AWS: Familiarity with the AWS Serverless stack and event driven architectures., • Customer Mindset: We value engineers who have a strong product and customer-centric mindset., • Communication: Excellent communication and collaboration skills to explain ideas clearly., • Collaborative and low-ego approach: You contribute positively to team culture and work well with others., • Agile: Comfortable with very lean/agile processes. We want you to be involved in all phases of the development lifecycle and bring your unique talents to the process., • DevOps: Experience with DevOps including setting up and managing CI/CD pipelines and terraform deployment., • AI enabled: Comfortable with leveraging AI to better assist developer workflows and rapid prototyping, • Testing: A strong testing mindset. If you think you meet most of the criteria, please get in touch! Experience we'd love to see: • Experience in developing high-scalability systems, • Experience with IoT data collection and processing pipelines. We are using a combination of Node-RED, MQTT, Telegraf, Linux, Python, InfluxDB and TimescaleDB., • Experience with integration of 3rd-party systems, • Experience with statistical modelling, ML optimisation & forecasting, • Strong data analytics skills, • Experience in early-stage start-ups, consulting, or high-growth environments where you've navigated ambiguity and taken initiative, • Experience working on (renewable) energy products or telemetry producing systems Location: • United Kingdom, Remote full-time, • We are remote first. We meet regularly (around once a quarter at least)., • We can’t currently support visas so you must have the right to work in the UK., • Preference for 1hr travel proximity to Edinburgh or Oxford to meet semi-regularly to work with founders or Head of Product. Remuneration: • £55,000 to £70,000/year salary depending on experience, • Share options in Logiq Systems

Lead Full-Stack Developer Location: Remote-first Type: Full-time Start: ASAP About Couch Heroes At Couch Heroes, we’re exploring new ground for the MMO genre. In a world where fantasy and ancient technology intertwine, players explore shattered realms, grapple across verticality, solve puzzles, and push back corruption, with progression driven by player expression and discovery. We envision bridging generations of gamers, creating a space where both coexist and journey together. We’re developing in Unreal Engine, in early production, with a team spanning multiple countries. We’re remote-first, based in the UK, and scaling to support a multi-year live-service roadmap. We value autonomy, curiosity, and collaborative ownership, and we’re looking for creators who want to help build something from the ground up. Sound like your kind of thing? We should talk. About the Job The web and platform layer of an MMO is what players interact with outside the game client: account systems, social features, community tools, content delivery, and the services that tie the live experience together. We need a Lead Full-Stack Developer who can own the architecture of these systems and build the engineering team that delivers them. You will report to the CTO and manage a growing team of web and platform engineers. You will make architectural decisions, stay hands-on with code, and represent the web engineering discipline across the studio in production planning and resourcing decisions. We are in early production. The studio has been running for three years, and core platform infrastructure is being built alongside the game itself. You will be making foundational choices about stack architecture, service boundaries, deployment pipelines, and data models that the team builds on for years to come. This is not a maintenance role. You are building systems from the ground up. Your Role People Leadership and Team Development • Manage a growing team of engineers as the team scales through production: set priorities, assign work, balance workload, and run regular 1:1s focused on progress, career development, and honest feedback., • Lead performance reviews and goal setting aligned to production milestones and individual development plans. Identify skill gaps and address them through coaching, stretch assignments, or training., • Represent the web engineering discipline in cross-discipline leads meetings, production planning, and resourcing conversations. Advocate for team needs and capacity., • Foster a team culture of code quality, shared ownership, and continuous improvement., • Support hiring as the team grows: contribute to job descriptions, review technical submissions, and participate in interview loops. Technical Leadership and Architecture • Architect and lead the development of backend microservices using TypeScript, Node.js, and Express, with MongoDB for persistent storage and Redis for caching, session management, and pub/sub messaging., • Design scalable, well-bounded services that support the throughput and reliability demands of a live-service MMO: player accounts, social systems, marketplace, mail, inventory, and platform integrations., • Own CI/CD pipelines using Azure Pipelines, with Docker and Kubernetes on Azure for container orchestration and deployment. Establish deployment practices that support rapid iteration without compromising stability., • Make architectural decisions about service boundaries, data models, caching strategies, and API design that balance immediate delivery needs with long-term scalability., • Establish monitoring, alerting, and incident response practices using Grafana and Uptime Kuma or equivalent observability tools. Frontend Engineering • Build polished, responsive, and accessible interfaces using TypeScript, React, and Next.js, with Redux for state management and Zod for schema validation., • Collaborate with UI/UX design to ensure clean design-to-implementation handoff and user-centric workflows across platform features., • Ensure frontend systems are built for internationalisation, accessibility, and performance from the start. Platform Integration • Work with gameplay engineering and online services to define how web platform systems integrate with the game client: authentication, account management, social features, content delivery, and analytics., • Collaborate with production to manage scope, schedules, and task breakdowns for web engineering work. Contribute to milestone planning, sprint scoping, and capacity forecasting. Must-Haves • Proven experience in software development, with at least one shipped product or live service., • Proven experience in a senior or lead role with hands-on team leadership experience: running 1:1s, setting goals, conducting reviews, and developing team members., • Strong backend experience with TypeScript, Node.js, and Express for API development., • Production experience with MongoDB and Redis in a services environment., • Strong frontend experience with React and Next.js., • Working knowledge of Docker, Kubernetes, and CI/CD pipeline design., • Experience with Azure Cloud services or equivalent cloud platform., • Strong communication skills and a collaborative working style, with proven experience making architectural decisions in cross-functional teams. Nice-to-Haves • Experience building backend services for games, social platforms, or real-time multiplayer applications., • Experience with Redux, Zod, or equivalent state management and validation libraries., • Familiarity with real-time communication systems: WebSocket at scale, pub/sub architectures, or event-driven service design., • Experience with Grafana, Uptime Kuma, or equivalent observability and monitoring tools., • Experience with OAuth2/JWT authentication flows and identity management., • Experience with Golang or additional backend languages., • Contributions to open-source projects or technical writing that demonstrates systems thinking. About You • You lead by example. You are hands-on when needed and empowering always., • You build systems that last and take pride in readable, maintainable code., • You are comfortable translating product vision into technical decisions and explaining technical constraints to non-technical stakeholders., • You are comfortable working through ambiguity. Early production means not everything is defined yet, and you see that as an opportunity to shape the right architecture., • You balance engineering ideals with delivery pragmatism. You know when to build for the future and when to ship what works., • You work autonomously in a remote environment, proactively keeping your team aligned and your stakeholders informed., • We are committed to making our hiring process accessible.
